No. 855,091 2 Claims.(Cl. 114-208) This invention relates to an improved construction for ananchor, and more particularly to an anchor construction having an anchorbody including a pair of laterally spaced flukes, and adapted to beconnected to the usual anchor line by means of an anchor shank pivotallyconnected to the anchor body.

A general object of the invention is to provide an improved constructionfor such an anchor wherein provi- S101! is made for accommodatingswinging movement of the anchor shank from an aligned position with theflukes to limit positions disposed on either side of this alignedposition, and wherein the limit positions for the shank are defined bymeans engageable with the flukes.

Another general object is to provide an improved construction whereinthe means limiting movement of the anchor shank accommodatessubstantially equal angular movement of the anchor shank to either sideof an aligned position with the flukes.

A further object of the invention is to provide an improved constructionwherein the flukes of an anchor are provided with means positioning themat an acute angle relative to a bottom with the anchor on the bottom,and provision is made for the usual anchor line connected to the shankof the anchor to pull on the anchor in a direction opposite to the onethe flukes are pointing (as when removing the anchor) with the pullexerted at a location substantially coinciding with the rear ends of theflukes and with the anchor line substantially unencumbered by the meanspositioning the flukes at said acute angle.

A still further object of the invention is to provide an anchor with thefeatures hereinabove described which is simple in construction, andcapable of mass production at relatively small unit cost.

Other objects and advantages are attained by the invention, such beingdescribed hereinbelow in conjunction with the accompanying drawings,wherein:

FIG. 1 is a side elevation of an anchor constructed according to thisinvention;

FIG. 2 is an end view of the anchor illustrated in FIG. 1 showing indashed and solid outlines various positions for the anchor shank;

FIG. 3 is a perspective view of the anchor; and

FIG. 4 illustrates the anchor as it rests on a river bottom and prior topulling on an anchor line to effect removal thereof.

Referring now to the drawings, indicates generally the anchor of theinvention, comprising an elongated shank portion 12 by means of whichthe anchor is attached through the usual anchor line to a vessel, and apair of laterally spaced and oppositely disposed flukes, indicated at 14and 16. These are flat, and occupy a common plane. The forward ends 14a,16a of flukes 14, 16 are pointed, thus to enable them better topenetrate the usual bottom. The flukes are triangular in shape, andtheir inner edges converge to define a throat for the anchor indicatedat 17. The substantially V-shaped throat is constructed to cradle a rockor other obstacle on a bottom, whereby the anchor may better be heldfrom shifting.

Interconnecting flukes 14, 16 is a rod or bar portion 18. This issecured as by welding to the rear ends 14b, 16b of the flukes, and isparallel to the plane of the flukes. To the rear of the flukes andsecured to the flukes through ends of bar 18 are plates 22, 24. Eachplate is joined to an end of bar 18 at a location midway between theends of the plate, so that it extends approximately equal distances toeither side of the plane of the flukes. Plates 22, 24 occupy a commonplane that is normal to the plane of the flukes. The plates constitutemeans for supporting the anchor so that when it rests on a bottom, theflukes extend at an acute angle upwardly from their forward ends. Eachplate has a width substantially coextensive with the width of the rearend of the fluke directly in front of it.

An intermediate portion 18a of rod 18 spans the distance between theflukes and constitutes a spindle portion in the construction. Shankportion 12 is pivotally connected to the anchor by means of a sleeve 36rotatably mounted on spindle portion 18a. The sleeve has a lengthslightly less than the distance between the flukes, and the flukesconfine the sleeve from lateral movement on spindle portion 18a.

In the embodiment shown, shank portion 12 takes the form of an elongatedU-shaped bar that has its ends Welded to sleeve 36. The space 38 betweenthe legs of the bar constitutes an elongated runway extending along thelength of the shank. An anchor line, such as the anchor chain indicatedat 40 in FIG. 4, is connected to the shank by linking the last link ofthe chain through runway 38. The runway accommodates shifting of the endof the anchor line longitudinally of shank portion 12.

In the construction, stop means is provided inhibiting pivotal movementof the shank portion after the shank portion has moved substantiallyequal angular distances to either side of an aligned position with theflukes, as best shown in FIG. 2. This stop means comprises a bar 46secured as by welding to shank 12, and having ends that extend overflukes 14, 16 and plates 22, 24. In one limit position for the shank,illustrated in solid outline in FIG. 3, the ends of bar 46 abut theinner faces of one set of ends of plates 22, 24, to prevent furthermovement in a clockwise direction. In the other limit position for theshank portion, indicated in dotted outline in FIG. 3, the ends of bar 46engage one set of faces of flukes 14, 16 to prevent further movement ina counter-clockwise direction.

Since the flukes and the plates are at right angles, the shank portionis limited substantially to movement through a 45 angle. Bar 46 ispositioned on shank portion 12 so that the angular movement of the shankto either side of an aligned position with the flukes is substantiallythe same. Thus the anchors operation is the same regardless upon whichside it rests when on bottom. Pivoted movement of the shank relative tothe flukes and plate 22, 24 is about an axis substantially coincidingwith the intersection of the plane of the flukes with the plane ofplates 22, 24, since bar portion 18 is disposed in the plane of theflukes and immediately adjacent the plane of plates 22, 24.

In operation, the flukes and plates 22, 24 of the anchor may assume theposition illustrated in FIG. 4 with the forward ends 14a, 16a of theflukes engaging a bottom and with one set of ends of plate portions 22,24 resting on the bottom thus to raise end 14b, 16b of the flukeswhereby the flukes angle into the bottom. When it is desired to removethe anchor by pulling the anchor rearwardly (or in a direction away fromthe pointed ends of the flukes), anchor line 40 is pulled toward therear of the anchor, which pivots the shank in a clockwise directionabout bar 18 until bar 46 strikes the inner faces of plates 22, 24.Continued pull on the anchor line, in the direction of the arrow in FIG.4, will then pull ends 14a, 16a from the bottom. Since the connection ofthe shank with the flukes is by means of a bar 18 located at the rearends and substantially in the plane of the flukes, the pull of theanchor line on the anchor is exerted at a location substantiallycoinciding with the location of the fluke rear ends. The spacing betweenplates 22, 24 enables the anchor line to drop between the plates, andminimizes any tendency of the anchor line to twist or turn the anchorduring its removal.

It is claimed and desired to secure by Letters Patent:

1. In an anchor comprising a pair of laterally spaced and oppositelydisposed substantially flat fiukes disposed in a common plane and havingforward ends adapted to engage a bottom, and a plate for each flukejoined midway between its ends with the rear end of the fluke andextending normally to either side of the plane of the flukes, saidplates occupying substantially a common plane, the improvementcomprising a connecting bar interconnecting the two flukes and disposedadjacent and substantially parallel with the plane of the flukes and theplane of the plates, a sleeve journaled on a portion of said connectingbar intermediate the flukes having a length coextensive with the spacingbetween the flukes, an elongated anchor shank joined at one end to saidspindle portion, and a stop bar integral with the anchor shank andspindle portion for limiting movement of the anchor shank relative tothe fiukes, said stop bar having a portion extending over at least oneof the flukes and the plate joined thereto, said stop bar limitingmovement of the anchor shank in one direction by striking said one ofthe flukes and limiting movement of the anchor shank in the oppositedirection by striking the plate joined to said one fluke.
